Get Bypass Codes

Using CalNet Account Manager

We recommend printing bypass codes and storing them in a secure location as soon as you set up 2-Step

You can request passcodes by logging in to the CalNet Account Manager and selecting Get Bypass Codes at the bottom of the Device Control Panel screen.

Note: Passcodes are single-use only; you must enter a new passcode each time you verify. Duo deactivates any old, unused passcodes once you request new ones. 

Using Duo Mobile

Open your Duo Mobile App. Click on "CalNet - UC Berkeley". A single-use passcode will display.

Did you know? You can use a passcode from the Duo App to complete the 2-Step on your smart phone from anywhere in the world -- even if you do not have a wifi or cellular connection!
